Which of the following is a common problem with condensers?

The accumulation of dust and dirt is indeed a common issue with condensers in HVAC systems. When dirt and debris build up on the condenser coils, it can impede the heat exchange process, leading to reduced efficiency and performance. This can cause the system to work harder to achieve the desired temperature, ultimately resulting in increased energy consumption and potentially leading to overheating or premature system failure.

Regular maintenance, including cleaning the condenser coils, is vital to ensure efficient operation. It is important to keep the outdoor unit clear of obstructions such as leaves, dirt, and other debris that can block airflow. By maintaining clean condensing units, you can optimize performance and extend the lifespan of the HVAC system.
